Potassium, Boron, Lead, Gold, Plutonium, Uranium, Francium
This is a covalent bond.
Boron Family
Hydrogen, Helium, Lithium, Beryllium and Boron.
Yes, borane (BH3) is a polar molecule since it has polar covalent bonds between boron and hydrogen atoms. The electronegativity difference between boron and hydrogen atoms leads to an uneven distribution of electrons, creating a partial positive charge on boron and partial negative charges on hydrogen atoms.
Uranium does not belong as it is a metal, while salt, boron, and hydrogen are nonmetals.
Uranium does not belong in this group because it is a radioactive element, while boron, salt, and hydrogen are all non-radioactive substances.
Salt, because it's a compound. Uranium, boron, and hydrogen are elements.
Salt doesn't belong because it is a compound, while the others are elements.
Hydrogen does not belong, as the other three elements are all metals while hydrogen is a non-metal.
First of all, don't ask us the questions in your homework. Secondly, you should be able to tell which three are elements and which is a compound. If not, you probably shouldn't be taking a chemistry class.
Uranium, boron, and hydrogen are all chemical elements. Uranium is a radioactive metal used in nuclear reactions, boron is a nonmetallic element often used in industrial applications like borosilicate glass, and hydrogen is a nonmetallic gas that is the most abundant element in the universe. Each element has its own unique properties and chemical behavior.
Boron is lighter than carbon and uranium.
Boron belongs to the family of elements known as metalloids or semimetals.
nonmetal
